Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 7 generators on 24 points:

(5,6)(7,8)(9,10,12,11)(18,21)(19,23);(6,7)(19,23)(22,24);(10,11)(14,16)(18,21)(22,24);(6,7)(13,14)(15,16)(17,18)(19,24)(20,21)(22,23);(3,4);(5,7,8,6)(9,11,12,10)(17,19)(18,22)(20,23)(21,24);(1,2)(3,4)

Conjugacy classes & character table

392 conjugacy classes. The character table is too large to display.

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((5,6)(7,8)(9,10,12,11)(18,21)(19,23), (6,7)(19,23)(22,24), (10,11)(14,16)(18,21)(22,24), (6,7)(13,14)(15,16)(17,18)(19,24)(20,21)(22,23), (3,4), (5,7,8,6)(9,11,12,10)(17,19)(18,22)(20,23)(21,24), (1,2)(3,4));
